Customer Reviews

Great dictionary

Great dictionary but I will not give it 5 stars because of the number of ads. Understand that ads are needed but the number and frequency are annoying.

Too many ads

I used to enjoy this app and use it frequently but the sudden surge of pop up ads make it a hassle to use. I will be using a different dictionary app from now on.

Far too many pop-ups

Fantastic dictionary, smoothly functioning app, weighed down by its excessive number of pop-up "upgrade to premium" ads or the smarmy "You're smart!" pop-up notices. Every time I open the app, I am bombarded by a pop-up hindering me from actually using the dictionary or thesaurus.

Furthermore, after writing this review, the developers sent me a generic automated email saying they wanted to "hear more about [my] current issue with the app." I don't want their emails in my inbox, *especially* if they aren't going to bother reading what I've written or address the problem. It's akin to spam.
